About Wall Lake Dam
The primary purpose of Wall Lake Dam is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Julius Wall (private). It impounds the Tr-nordston Creek near Warsaw.
The dam stands 20 feet tall and stretches 330 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 268 acre-feet, and collects water from a drainage area of 179 square miles. Completed in 1972, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
